Do All Bases Have a pH Greater Than 7?

💡 The Answer

• In aqueous solutions, bases always exhibit a pH above 7 due to high concentration of hydroxide ions.
• The pH scale is designed for water; in non-aqueous solvents, bases may not follow the same pH behavior.
• Some strong organic bases, like lithium diisopropylamide, work in non-aqueous environments where pH is not defined.
• The concept of pH strictly limits the scale to 0-14 in water, but bases in other solvents can exceed this range.
